advancedRevision notes
Key points
- The nervous system controls rapid responses using electrical impulses.
- A neuron is the structural and functional unit of the nervous system.
- Reflex action is a quick automatic response to a stimulus.
- Hormones coordinate slower and longer-lasting responses.
Nervous coordination
Receptors detect stimuli and send impulses through sensory neurons.
The brain and spinal cord process information and send motor responses.
Hormones and plants
Endocrine glands secrete hormones directly into blood.
Plants show movements in response to light, gravity, touch, and chemicals.
Quick practice
- Draw and label a neuron.
- What is reflex action?
- Name two plant hormones.
